• part 2 of ​https://bugs.webkit.org/show_bug.cgi?id=20858 make each distinct C++ class get a distinct JSC::Structure

+ Fixed all cases where we were using a shared structure for multiple

C++ classes in WebCore. This still has to be done in JavaScriptCore.

+ Got rid of cacheGlobalObject.

+ Improved use of PassRefPtr in bindings code.

+ Removed a couple cases where we were potentially allocating prototypes

inside a JSObject's construction process -- this can lead to trouble if
we do a garbage collection while an object is only partly constructed.

• bindings/js/JSAudioConstructor.cpp: (WebCore::JSAudioConstructor::JSAudioConstructor): Create a structure explicitly so we don't implicitly share the structure with other objects that use the object prototype.

• bindings/js/JSDOMBinding.cpp: (WebCore::getCachedDOMConstructor): Added. To be used for constructors so we don't need cacheGlobalObject any more. (WebCore::cacheDOMConstructor): Ditto.

• bindings/js/JSDOMBinding.h: Removed DOMObject constructor that takes a prototype. Added functions and a function template for getting cached DOM constructors. Removed cacheGlobalObject function template.

• bindings/js/JSDOMWindowBase.cpp: (WebCore::JSDOMWindowBase::JSDOMWindowBase): Take a PassRefPtr<DOMWindow> since we're taking ownership.
• bindings/js/JSDOMWindowBase.h: Changed constructor to take PassRefPtr, since we're taking ownership. Added constructor map.
• bindings/js/JSDOMWindowCustom.cpp: (WebCore::JSDOMWindow::mark): Mark the constructors in the map.

• bindings/js/JSDOMWindowShell.cpp: (WebCore::JSDOMWindowShell::JSDOMWindowShell): Take a PassRefPtr<DOMWindow> since we're taking ownership. Use the new setWindow function to create the JSDOMWindow; this is now done in only that one place. (WebCore::JSDOMWindowShell::setWindow): Added. Creates the JSDOMWindow based on the passed-in DOMWindow. Code was moved here and changed to allocate unique structures for both the window prototype and the window.
• bindings/js/JSDOMWindowShell.h: Ditto.

• bindings/js/JSEventTargetBase.h: Changed class template argument so it doesn't have the same name (JSEventTarget) as an actual class. Removed unhelpful use of private/friend in JSEventTargetBase. Removed comments referring to defunct macros. Changed JSEventTargetBasePrototype to get the prototype with the new rather than its own copy of cacheGlobalObject (I missed this during pass 1). Changed JSEventTargetBasePrototype so it doesn't have so many template arguments.

• bindings/js/JSEventTargetNode.cpp: Added s_info; needed for the new scheme for caching structures and prototypes. (WebCore::JSEventTargetNode::JSEventTargetNode): Use PassRefPtr. (WebCore::JSEventTargetNode::createPrototype): Added.
• bindings/js/JSEventTargetNode.h: Updated for above changes.

• bindings/js/JSHTMLAllCollection.h: (WebCore::JSHTMLAllCollection::JSHTMLAllCollection): Use PassRefPtr.
• bindings/js/JSHTMLCollectionCustom.cpp: (WebCore::getNamedItems): Pass ExecState instead of prototype.
• bindings/js/JSHTMLFormElementCustom.cpp: (WebCore::JSHTMLFormElement::nameGetter): Ditto.
• bindings/js/JSHTMLInputElementBase.cpp: (WebCore::JSHTMLInputElementBase::JSHTMLInputElementBase): Use PassRefPtr.
• bindings/js/JSHTMLInputElementBase.h: Ditto.
• bindings/js/JSHTMLOptionElementConstructor.cpp: (WebCore::JSHTMLOptionElementConstructor::JSHTMLOptionElementConstructor): Create a unique structure instead of sharing.
• bindings/js/JSImageConstructor.cpp: (WebCore::JSImageConstructor::JSImageConstructor): Ditto.

• bindings/js/JSInspectedObjectWrapper.cpp: (WebCore::JSInspectedObjectWrapper::wrap): Removed overload that takes a prototype rather than a structure. Made the use of inheritorID() here explicit.
• bindings/js/JSInspectedObjectWrapper.h: Ditto.
• bindings/js/JSInspectorCallbackWrapper.cpp: (WebCore::JSInspectorCallbackWrapper::wrap): Ditto.
• bindings/js/JSInspectorCallbackWrapper.h: Ditto.

• bindings/js/JSNamedNodesCollection.cpp: (WebCore::JSNamedNodesCollection::JSNamedNodesCollection): Changed to take an ExecState argument instead of a prototype. Create a unique StructureID instead of sharing.
• bindings/js/JSNamedNodesCollection.h: Ditto.

• bindings/js/JSQuarantinedObjectWrapper.cpp: Removed overloaded constructor that takes a prototype instead of a structure.
• bindings/js/JSQuarantinedObjectWrapper.h: Ditto.

• bindings/js/JSRGBColor.cpp: (WebCore::JSRGBColor::JSRGBColor): Take ExecState instead of a prototype; create a unique structure. (WebCore::getJSRGBColor): Ditto.
• bindings/js/JSRGBColor.h: Ditto.

• bindings/js/JSSQLResultSetRowListCustom.cpp: (WebCore::JSSQLResultSetRowList::item): Use constructEmptyObject instead of explicit coding the idiom for making a new object.

• bindings/js/JSXMLHttpRequestConstructor.cpp: (WebCore::JSXMLHttpRequestConstructor::JSXMLHttpRequestConstructor): Create a unique structure instead of the shared one.
• bindings/js/JSXSLTProcessorConstructor.cpp: (WebCore::JSXSLTProcessorConstructor::JSXSLTProcessorConstructor): Ditto.

• bindings/js/ScriptController.cpp: (WebCore::ScriptController::clearWindowShell): Let the window shell's setWindow function create the JSDOMWindow instead of doing it here.

• bindings/scripts/CodeGeneratorJS.pm: Changed to use PassRefPtr for the structure and the wrapped object when creating wrappers. Simplified some of the special cases for DOMWindow so they are different only in ways the need to be. Eliminated the JSDOMWindow::createPrototype and JSDOMWindowPrototype::self functions. Moved responsibility for creating the structure and parent prototype out of the prototype constructor into the createPrototype function. Removed the unused "DoNotCache" flag for objects other than DOMWindow. Use getDOMConstructor instead of cacheGlobalObject for constructors. Make each constructor have a unique structure ID.

• bridge/objc/objc_runtime.h: Added createPrototype and changed the name of the info member to s_info so we can use the standard DOM binding macros to handl the prototype.
• bridge/objc/objc_runtime.mm: Fixed namespacing a bit. (JSC::Bindings::ObjcFallbackObjectImp::ObjcFallbackObjectImp): Create a unique structure using getDOMStructure.

• bridge/runtime_array.cpp: Fixed namespacing a bit. (JSC::RuntimeArray::RuntimeArray): Create a unique structure using getDOMStructure.
• bridge/runtime_array.h: Added createPrototype so getDOMStructure will work.

• bridge/runtime_object.cpp: (JSC::RuntimeObjectImp::RuntimeObjectImp): Create a unique structure using getDOMStructure.
• bridge/runtime_object.h: Added createPrototype so getDOMStructure will work.

• history/CachedPage.cpp: (WebCore::CachedPage::restore): Let the window shell's setWindow function create the JSDOMWindow instead of doing it here.

• page/DOMWindow.idl: Removed DoNotCache, which is no longer used.
